“Estimated today” is a modeled figure, not an appraisal: each realized price is adjusted by the change in ALT/FNDATA’s trophy-tier price level for its category (the median of comparable high-value lots, from the sale year to the present). It is a market-level estimate; individual pieces vary, and categories without enough comparable high-value data are shown as insufficient to estimate.
Notable historical collection. The realized figures are public auction results, from the dates shown. “Estimated today” and the value chart are modeled market estimates, not a live valuation or appraisal, and not a current holding.
